IMPROVEMENT IN HO RSE HAY-RAKES.

Specification forming part of Letters Patent No. 214,497, dated April 22, 1879; application filled September 24, 187 8.

To all whom it may concern.-

Be it known that I, REUBEN ELLwooD, of Sycamore, DeKalb county, State of Illinois, have invented new and useful Improvements in Horse Hay-Rakes, of which the following is a full. description, reference being had to the accompanying drawings, in which- Figure 1 is a top or plan view; Fig. 2, a cross-section; Fig. 3, a section on linel 2 of Fig. 2; Fig. 4:, a top view of the parts between the thills, enlarged; Fig. 5, a cross-section on line 3 4 of Fig. 4; Fig. 6, a longitudinal section on line 5 6 of Fig. 4 Fig. 7, an under or reverse view of the parts shown in Fig. 4.

My improvements relate to that class of horsehay-rakes known as self-dumpers, where the rake-head is disconnected from the axle; and the invention consists in the construction and combination of devices for automatically operating the rake from the axle and adjusting the throw of the same, and also in the constrnction and combinations of devices for operating the rake by a treadle, all substantially as hereinafter more-fully set forth.

In the drawings, A indicates the axle; B B,

'the wheels; 0, the rear bar, upon which the rake-head is mounted; D, the rake-head; E, the slotted rear guide for the teeth; F, the teeth; G, the thills; H H, cross-bars connecting the thills together; I, drivers seat J J, bars between the thills for supporting'and operating the clutch-levers; K, whiffletree; L, hand-lever for discharging the rake; M, lever block or arm by which the tilting devices are connected with the rake head or frame; N, brackets or castings by which the slotted guide-board E is supported in position;O, boxes or axle-bearings; O, straps or claspbands for securing the axle-bearin gs; 1?, couplin gs or hinged standards, by means of which the rake-head is supported on the main frame or:bar';O ';"a, treadle having an under projection, I); b b,'"rods connecting the treadle with the" outer; end of the clutch-levers; 0, spring for holding the clutches out of contact by its action on the clutch-levers; (I d, clutch-levers e e, side projections on the rear ends of the levers 01; ff, yokes for operating the clutches; g g,clutches; h, lever-head, upon which the clutches operate; 2', incline or wedge operating upon the inclines e of the lever projections c to spread or detach the clutches; jj j,

supporting-plates for the levers d, forming also the connections between the bars J J k, arm or lever of the head h; I, enlarged upper end of the arm 70, having one side radially serrated, and

having also a slot, through which the set-screw justed, so as to bring the hand-lever L within convenient reach of the driver or operator; 1*,

rear projecting arm of the lever L; s, bracket, to which the lever L is pivoted; t, a plate located beneath the bar 0, and having a projection fitting the groove t of the head h to prevent the head from moving along the axle, so as to come in contact with either clutch; to, covers or housings to keep hay or dirt out of the clutches; v, joint in the standards P; 'w, screw-rod or bolt passing through the head D; 00, upper, and 3 lower, screw-nuts, by means of which the rake-head D canbe raised orlowered, and the rake-teeth adjusted to their proper relative positions; and z, sockets, into which the bent upper ends of the teeth are inserted to enable them to articulate or have independent movements. I The axleAis made to revolve with the wheels, which may be attached thereto with clutches or other suitable device to enable each to have a separate or independent movement in turning or backing.

The rake teeth and head are made in the ordinary manner, as shown, and the rake-head is connected with the main cross-bar by a jointed standard, 1?, Fig. 3, so that the rockin g or movement of the bar 0 on the axle will not disturb the teeth and in order to'adjust the height of the teeth, which also to a certain extent adjusts their pitch, I have provided the post to with a screw-thread and with a nut,

y, below and a nut, m, above, so as to adjust the height of the rake-head or the space between it and the bar 0; otherwise the rakeframe is made, and the teeth, seat, and thills, are attached, in the usual manner.

Between the thills I attach a secondary frame, composed of the bars J J and cross bars or plates jj j, and within this frame or between the bars J there is located upon the axle and turning upon it a lever-head, It, which has its ends provided with teeth or cogs corresponding with those of the clutches g. This head is made in two parts, both of which are firmly attached to the arm 70, or it is made of one piece and provided with agroove, it, into which the plate 25, Fig. 7, passes sufficiently far to prevent any end movement of this head It.

The arm 70 extends upward and has an enlargement, l, at its top, which is provided with teeth radiating from the pivot n, which teeth engage with corresponding ones on the side of the arm or section m. These teeth or notches are held in contact by the bolt or set-screw o passing through a slot in the part I, as shown. The slot, however, is not essential, as the part 1 may be a single curved bar with the setscrew or bolt placed above it; and aseries of holes in the head I, with a pin in the part m, may be used in place of the teeth or,serrations, although the teeth shown are preferred. By this arrangement the height to which the rake-teeth are to be thrown in discharging can be adjusted; for when the adjustment is made backward, the wedge 11 comes sooner in contact with the side arms a of the levers cl, and there is a less lift of the rake-teeth, and when adjustedforward the lift of the rake-teethisincreased. The block or arm Mis made of castiron, and is secured to the bars D and E by flanges and bolts, or by other suitable means, and is connected with the arm k on by the rod 1). It is also connected with the hand-lever L by the rod or bar q.

The clutches g are made to move along the axle A bymeans of a feather and spline or groove and pin, and revolve with the axle. They are moved back and forth by the forks f of the levers d, fitting in suitable grooves therein, as shown. The levers d are pivoted to the plate j, and are provided with side projections e, which rest upon the plate j, to prevent the turning or cramping of the levers.

The side projections e have their upper inner corners inclined at 0, so that the wedgeor incline i will act thereon to detach the clutches by spreading the levers without unnecessary friction or wear. The incline or wedge i is firmly attached to the head it or to the arm 70, and its sides are inclined, so as to spread the levers din its forward or descending movement, and thereby release the clutches 9. Near the forward end of the levers d a spring, a, is placed, which spring operates to throw or force the ends of the levers toward each other, and thus keep the clutches 9 out of contact with the head h. It also operates to draw the rods 1) together, and thus lift the treadle a and keep it in position.

The tension of the spring is regulated by with the levers d at their lower ends and to the treadle a at their upper ends by means of a projection, b, or directly, as may be desired. These rods stand at an angle, so that a downpressure on the treadle operates to spread the levers d and throw the clutches into contact or gear with the head h.

The hand-lever L is made and operated in the usual manner, and it is applied so that the rake may be used either as a self or a hand dumper.

The part r of the handdever is so connected with the rod q that they can be adjusted and operate as a stop in connection with the arm M to limit the downward movement of the rake-teeth. The hand-lever is also so connected with the arm M, and through that with the arm m k, that it may be used to force 'the clutches out of contact with the head h if for any reason the spring 0 should fail to act.

The rod q may be extended, and its fork connected with the lever L above the pivot, so as to dispense with the part r and reverse the movement of the lever from a pull to a push.

The head or enlargement l at the upper end I of 70 may have teeth on each side, and two arms may be used above, one on each side, instead of the single arm on, and a bolt might then be used in place of the set-screw 0.

What I claim as new, and desire to secure the lever M, attached to the rake-head, disconnected from the axle, substantially as and.

for the purposes herein set forth.

2. The combination of the head h and wedge or incline 'i with levers cl, having side projections or arms 0, substantially as specified.

3. The combination of the head h, incline i,

and clutches g g with the levers d,having side projections c and forks forth.

4. The combination of the treadle a, rods Z1.

spring 0, and levers d with the clutches g and head h, substantially as described.

5. The combination of the treadle a, rods b, levers d, having side projections e, and the spring 0 with the clutches g g, head h, and incline or wedge i, substantially as specified.
